DATA LIST / ACTIVE TEST
1. READ DATA LIST
HINT:
Using the intelligent tester's DATA LIST allows switch,
sensor, actuator and other item values to be read without
out removing any parts. Reading the DATA LIST early in
troubleshooting is one way to save time.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Turn the intelligent tester on.
(d) Read the DATA LIST according to the display on the
tester.

2. PARFORM ACTIVE TEST
HINT:
Performing the intelligent tester's ACTIVE TEST allows
relay, VSV, actuator and other items to be operated
without removing any parts. Performing the ACTIVE
TEST early in troubleshooting is one way to save time.
The DATA LIST can be displayed during the ACTIVE
TEST.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Turn the intelligent tester on.
(d) Perform the ACTIVE TEST according to the display
on the tester.
HINT:
• The ignition switch must be turned ON to
proceed to the ACTIVE TEST using the
intelligent tester.
• The ACTIVE TESTs of the ABS solenoid, ABS
motor relay, ABS warning light and BRAKE
warning light are available when the vehicle is
stopped.
• The motors stop automatically after 5 seconds of
activation to prevent them from being damaged.
When the motors are driven repeatedly, certain
intervals are required.
• Each solenoid stops automatically after 2
seconds of activation to prevent them from being
damaged, and can be operated again after a
certain interval.
• Do not depress the brake pedal while only the
pressure reduction solenoid valves are on.
• Do not drive 2 or more solenoids simultaneously
except to operate the pressure holding solenoid
valves and pressure reduction solenoid valves of
each wheel.
